That's why I ride the short bus!! There's room in the back if you wanna come for a ride...you can invite Chris!!

 

Julien,
you running 2 bar or 3 bar?

 

Ya the CR plays a big role in that.

 

As does blower efficiency and IAT's.

 

The MP122HH at 15 psi actually runs around 108-118 IAT's in around town driving with the TrailBlazer SS. I actually find that during a WOT run the IAT's will drop during the run and they only spike after the throttle blade shuts when you let off of it. It is amazing because if you go right back to cruising it will cool itself right back down to the 108-118 IAT's almost immediately. I did add a secondary heat exchanger with 2 more psi of boost just recently and saw a drop of almost 4 degrees with around town driving. The MP1900 at the RPM's you will be running should have very similar IAT's when built around the same platform. Make sure to run a set of 1 7/8 primary headers and a dual 3" exhaust system to ensure you are getting the heat out of the heads.

 

3 bar for his year. Go figure eh Mark?

 

Jullien
YOU SUCK

 

its OK, my 14 psi against your 18psi and my 900lbs more, we shall see

 

And my 10psi against your 14psi

I am interested to see the results of this setup.

 

Is the L92 system using the same intercooler as the older MP112's? I remember seeing somewhere that they are available now, but I haven't gotten to play with one yet and really want to see what they can do. I was hoping that the new lower intake would have an intercooler similar to that of the LS9 which has an impressive intercooler system.

I know the MP112's and MP122HH's I've worked with have had IAT issue's. I do understand that the front inlet, 90mm throttle body, and larger maf really help reduce restriction which gains you boost without the blower having to work so hard to get you there, but those kind of IAT's are just amazing for how fast yours must be spinning. Very cool.
